FEATURES The Fat Boy® is deserving of its name especially now that it’s powered by the Twin Cam 88B™ engine. There’s nothing skinny about this machine: fat FL forks, a black and chrome engine treatment, shotgun exhaust, full-sized floor boards, and broad handlebars make people notice this bike in a crowd. A 7-inch chrome headlamp, textured leather seat insert and a hand-laced leather tank panel add to the distinctive look.
